Toyota Motor Corp. will introduce systems in about two years enabling cars to communicate with each other to avoid collision.

The system will use radio waves to gather data on the speed of other vehicles to keep a safe distance. And, the company also showed another system, consisting of cameras, radar and control software, that helps a car maintain position in a lane on its own.

I can see where a technology like this might offer some safety, but I am equally sure that some as-yet-not-discovered risks exist with this technology that we will realize only AFTER it is deployed. Why? Because that has been the history of technological innovation.

Toyota said the problem is due to water leaking from the air conditioning condenser unit onto the airbag control module. The leak could also result in additional problems, potentially causing a short circuit that would disable the power-steering system. In this case, it could become difficult to turn a vehicle, especially at lower speeds. Yup anouther toyota recall ... here we go again.
